The International Space Station is now home to more than 1,200 pounds (544 kilograms) of supplies delivered by an unmanned, privately built space capsule that reached the orbiting science laboratory on Sunday (March 3). <\/p>\n
Among the goods SpaceX's Dragon capsule transported to the station were science experiments primed and ready for the six international residents of the space station. <\/p>\n
\"Dragon is scheduled to return to Earth on March 25, bringing home nearly double the amount of supplies it brought up, about 2,668 pounds (1,210 kilograms),\" NASA officials said in a statement. \"Returning investigation samples will demonstrate how life in microgravity affects the growth of plant seedlings, changes to the human body, the behavior of semiconductors and detergents, and more.\" <\/p>\n
Some of the experiments will only stay on board for three weeks, making a round trip back to Earth with Dragon when the capsule detaches from the station. One of those experiments involves thale cress, a plant used in many experiments because of its small, relatively easy-to-map genome. <\/p>\n
Scientists affiliated with NASA and the European Space Agency sent up one experiment called \"Seedling Growth-1,\" designed to investigate how well plants grow amid stresses such as low oxygen. [See video of SpaceX's Dragon docking in orbit] <\/p>\n
\"The experiment will study how plants adapt to micro- and low-gravity environments,\" NASA officials wrote in a statement. \"Researchers hope to determine the ability of vegetation to provide a complete, sustainable, dependable and economical means for human life-support in space.\" <\/p>\n
Beyond helping scientists learn how to grow food in space, the research might contribute to better agricultural practices back on Earth. Understanding how these plants react to a stressful environment could lend insight into how farmers could mitigate those taxing situations back on the planet's surface. <\/p>\n
Some of the experiments sent to theInternational Space Station will play a role in education, as well. <\/p>\n
\"Students from several California schools developed investigations to study bacteria, iron corrosion, battery performance and carbon dioxide levels aboard the station, all of which will be delivered by Dragon,\" NASA officials wrote in a statement. <\/p>\n
Personal product manufacturer Procter & Gamble sent up another experiment that will study how to better preserve toothpaste, gels and creams. <\/p>\n
